Senior AI Engineer

At Jack Henry, we're more than a technology company, we're a force for good in financial services. We're redefining how community banks and credit unions connect with the people they serve. Our mission is rooted in people inspired innovation, empowering financial institutions to deliver seamless, secure, and human centered experiences. We deliver cutting-edge solutions that are paving the way for the next generation of digital banking and payments, but our true impact begins with our associates. If you're ready to help transform an industry and grow with a company that values purpose, collaboration, and excellence then we'd love to meet you.

Jack Henry's AI Platform team is hiring a Senior AI Engineer to turn promising prototypes into systems people can depend on. We build the platform that AI runs on at Jack Henry, consisting of projects like:

• The Garage - our hosting platform for vibe-coded apps built by people across the company who mostly aren't engineers
• The AI Gateway - routes and governs AI requests enterprise-wide
• MCP servers connecting agents to our core banking systems
• Self-hosted inference

Most of it started as someone's proof of concept. Your job is to make it production-ready:

• reliable AI workflows with real validation, error handling, retries, logging, and fallback behavior
• evals and automated testing for agentic systems that don't behave deterministically
• monitoring that tells us quality has drifted before a user does

You'd work directly with the internal users who built those POCs, shaping them into software and workflows that hold up. You'd bring in our experts across cybersecurity and cloud infrastructure rather than guessing at their standards, partner with our AI coaches so others can actually use what we build, and mentor engineers earlier in their careers. You'd also use agentic workflows to do the work itself - we build with these tools, not just on top of them.

We're looking for someone who has shipped scalable, maintainable production software and has run AI systems in production rather than only prototyped them. You'll need comfort with change and a bias toward action - this is early work on a small team.

Financial services adds a constraint most AI work doesn't have: everything we ship has to be observable, auditable, policy-bounded, and explainable. That combination - real AI engineering under real regulatory constraint - is a rare and durable skill set, and there aren't many places to build it. You'd help us carve out the agentic future at Jack Henry.

This position is a hybrid role requiring at least 1 day per week in any of the following office locations: Allen, TX, Louisville, KY, Birmingham, AL, Cedar Falls, IA, Charlotte, NC, Lenexa, KS, Monett, MO or Springfield, MO.

This position is ineligible for immigration sponsorship and support. Please do not apply if at any time you will need immigration support now or in the future (i.e., H-1B, PERM).
